Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18164, here are decompositions:
- 31 + 18133 = 18164
- 37 + 18127 = 18164
- 43 + 18121 = 18164
- 67 + 18097 = 18164
- 103 + 18061 = 18164
- 151 + 18013 = 18164
- 193 + 17971 = 18164
- 241 + 17923 = 18164
Showing the first eight; more decompositions exist.
